I'm seeing the same phenomenon on one of our LANs (on another LAN, I don't see it). My setup is with RHEL 7, and it is seen on both physical and virtual servers. I don't see it on any RHEL 5 or 6 servers. A strange observation: If I start tcpdump, the package drops stop. (Setting the NIC in promisc mode does not have any impact; it has to be tcpdump.) I suspect that it has to do with this: https://www.netiq.com/support/kb/doc.php?id=7007165 If this is the case, it's simply because recent kernels classify packets, and then there's nothing to worry about. - But Red Hat Support does not share that view. I have an open case with Red Hat Support about it; lots of stuff has been tried, but we have yet to reach a conclusion. -- Troels
